“…Participants highlighted that autonomous care of green infrastructure could lead to the simplification of ecosystems, with negative consequences for biodiversity 13 . This would be the likely outcome if RAS make the removal of weeds and leaf litter and herbicide application substantially cheaper and quicker, such as through the widespread uptake of robotic lawn mowers or tree-climbing robots for pruning 52 . Urban ecosystems can be heterogeneous in habitat type and structure 51 and phenology 53 .…”

W e are currently witnessing the fourth industrial revolution 1 . Technological innovations have altered the way in which economies operate and how people interact with built, social and natural environments. One area of transformation is the emergence of robotics and autonomous systems (RAS), defined as technologies that can sense, analyse, interact with and manipulate their physical environment 2 . RAS include unmanned aerial vehicles (drones), self-driving cars, robots able to repair infrastructure, and wireless sensor networks used for monitoring. RAS therefore have a large range of potential applications, such as autonomous transport, waste collection, infrastructure maintenance and repair, policing 2,3 and precision agriculture 4 (Fig. 1). RAS have already revolutionized how environmental data are collected 5 and how species populations are monitored for conservation 6 and/or control 7 . Globally, the RAS market is projected to grow from $6.2 billion in 2018 to $17.7 billion in 2026 8 .Concurrent with this technological revolution, urbanization continues at an unprecedented rate. By 2030, an additional 1.2 million km 2 of the planet's surface will be covered by towns and cities, with ~90% of this development happening in Africa and

“…Another robot that does a good job maneuvering in a complex 3D environment is Tree Bot (Lam and Xu, 2011a,b). Tree Bot has a pinion gear to drive axial movements along three rod-like springs that serve as a backbone and a pair of two-bar articulated legs each with linear actuators to control gripping.…”

A soft climbing robot has the potential to access locations such as wiring ducts and tree canopies that are unreachable by humans and traditional rigid robots. In addition, a soft robot is robust and can fall without damaging itself or its environment. We present a soft, branch-crawling robot that is inspired by the passive gripping mechanisms used by caterpillars. The conformability of the robot’s soft body makes it uniquely suited to move in a complex 3D environment. A key innovation is that grip release is actively controlled and coordinated with propulsion generated by stored elastic energy. The robot is molded from silicone rubber and actuated using remote motor-tendons coupled to the structure through Bowden cables. Grip is achieved passively through an elastic flexure that pushes a compliant finger against the dowel. Experimental results show that the gripper is easily able to support the weight of the robot, and that the body structure allows the robot to crawl horizontally, vertically, and along branches. This robot demonstrates some key advantages of a soft robotic platform over traditional rigid robots.

“…Full et al 8 proposed a bionic robot, RHex, to maximize effective distributed leg contact through changing leg orientation and adding directional spines, which improved RHex's ability on some challenging surfaces without adding any sensors. Lam et al [9][10][11] designed a tree-climbing robot that could cross tree-like branches and had a claw-type and new flexible motion structure. The robot weighed 600 g and could bear a load up to 1.75 kg.…”

Climbing robots have been widely used to inspect smooth walls. However, a good adsorption method has not been found for the inspection of a cliff surface and a dusty high-altitude surface with small vibration, both of which are made of coarse concrete, square brick, or rock. In this article, first, we analyzed the bionic structure of the cockroach legs and observed their morphological characteristics of the spiny claws on these legs. We also studied the interaction theory of the bionic claw with the bulges on the rough wall surfaces and deduced the mechanical criteria of the claws grabbing steadily these bulges. Then, an initial mechanical structure of a wall-climbing robot was proposed based on a grasping claw and a climbing model. Furthermore, a mathematical model was established to reflect the relationship between sharp hooks and bulges on the rough wall. Finally, we performed several laboratory experiments to verify the grasping stability.
